To kall whom tnncy/ concern: K

Beit knownvthatl, EDWARD KnNnmJr., a citizen of the` United States, 4residing at Buffalo, in the county offFirie and State. of New York, have invented anew and useful Improvement in Incinerators, of which the following isa spe,c'ilicatio-n...f` y

This inventionrelates to an incinerator which isinore particularly designed/for use in households or'litchens for Ythe purpose of making it easily `possible to consume kitchen refuse andsimilar material.A

It isthe object o'thisv invention to provide ank incinerator Vof this character which will'.completely.consume all of the refuse of various kinds. whichr are ordinarily accumulated in; kitchenfand `burn the same so thoroughly that only `dry ashes remain and no perceptible odors. escape to theexterior ofthe lincineiator.forto the outsidev ot' the building,ithereby avoiding' offense to neighbors aswell as to thezpersons operating the incinerator. ,f 1 *i In the accompanying drawings:

Similar characters ofwreference indicate The numeral lO'represent-s the combustion chan'lberor refuse receptacle which is vdesigned. to receiveythe4 refuse-or garbage: which is to be burned, this material being introduced through an .inlet l2 in the upper part of this `chamber, which inlet isA normally closedby meansoita ldoor 13.` VVit-hin this chambcris arranged an inner up right side wall V14 which supports the pile' of refuse l5 onits side, this wall being provided throughout its height and` at suitable intervals with s a., or openings 16.

Adjacent'to the outer side of this inner wall is arranged an outer wall 134" whichis pluralityv of pertorations tight or impert'orate and separated orspaced .apart from the-inner wall lll-so as to form an intervening conduit or space 18 there-v between. t This clearance kspace 18 opens at vits upper end into the upper part oi' the combustion chamber while its lower ends opens into the ash ptp19. This ash pit is. Vseparated from the combustlon chamber by; Y

vprefeiably extending upwardly from, the

centraly part'of thetop 21 thereof, is a iue or gas' disclia1'ge pipe 22, whereby the combustion chamber maybe connected with a chimney ot the' building or otherwise 4eX- tended to the exterior of the building forl the purpose of carrying olf any non-combus -tible` gases which are generated `by the incinerator.

Arranged on the central part of the'grate is bridge 23 which is preferably .made hollow and provided centrally onits upper part with an opening 24. Extending up- .wardlyfrom this'bridge is a vertically tele Ascopingl burner which is so mountedl that the same gradually descends inthe same Ymeasure as the pile of garbage vor reiuse'is :gradually consumed` from the top downwardly and therefore becomes less .in height. In its .preferred constructiony this telescopic burner consists of aplurality of sections 26, 27 and'QS which are of progressively reduced diameter from the lowerniost to the uppermostand slide one within the other in the `form of a telescope. The lowermost section 25 of this burner projects upwardly through the lopening Qdithrough the bridge .23 andiis provided with an upwardly facing flange.l or shoulder 29 which is ada ted to engage .with the underside of the bridge tor the purpose oi hunting the upward movevment of the Ylowerin'ost burn-er section and yalso the `ren'iaining sections which are tele` scopi'cally connected therewith. Each et NTg OFFICE.

(ill

the upper burner sections is also provided wit-h an upwardly facing annular shoulder or flange 30 whichr engages with a downwardly facing shoulder or flange 31 formed on the upper end of the next lower burner sect-ion and thereby serves as stopping means which limit the extent which the telescope. bui-ner can be distended upwardly or away from the bridge of the grate. rl`he uppermost burner section is provided in different parts of its side with a. plurality of gas outlet openings 32 and its uppereiid is also open so that `gas which is supplied to this burner at the lower end issues upwardly and laterally froinall directions so rthat upon igniting the gas which issues from the upper end of this burner the same will play a fiaine wliichengages with the upper part of tliefpile of garbage or refusein the combustion chamber. This gas is-supplied to the lower end of the burner by means of a gas delivery pipe or conduit 88 V7which is arranged in the ash pit close to the underside ofthe grate QO'and provided centrally with an upwardly projecting delivery nozzle 34 which directs the gas upwardly into the lower end of the burner, while the outer end of this burner is connected externally of the incinerator with a gas supply ,pipe 35 which is yconnected with any suitable source of supply.

Arranged within the upper part of the combustion chamber and adapted to be supported by or rest on the top ofthe pile of refuse is a spreading plate 36 which is preferablytof upwardly dished form` Instead of resting this spreading plate or disk directly upon `the pile of refuse, it is provided on its underside with aplurality of spacing ribs 37 which extend from the central partof the underside of the spreading plate tothe marginal'part.thereof, the. innerend of each of these ribs, however, terminating shortof the axis vof this spreading` plate so as yto leave a clear central space on the underside ofl this plate and each ofthe spacing ribs also preferably extending for a. short dist-ance beyond the marginal edge lof the spreading plate and within a short distance of the inner side of the inner wall l5, as shown .in Figure l. rihis spreading plate is connectedwith the uppermost section of the burner so that the same rises and falls together, this being preferably effected by means of a link 38 which is of T`shaped form andk engages its crosspiece with corresponding openings in the upper end of the uppermost burner section while its shank is secured in acentral opening inthe spreading plate, as shown in Figure Vl.

lt follows from this construction that whenever the spreading plate is raised or lowered, the telescopic sections of the burner will be extended or nested accordingly and that the height ofthe burner will therefore be governed by the vertical position of the spreading plate within the combustion chamber. As t-hegas'burns in a flame vagainst the upper part of the pile of refuse, the

same isdirected over the top of the same and caused yto overspread the pile of refuse by reason of the deflecting or bafiing action ofthe-spreading plate 3G which compels this flame to lie close to the top of the pile of refuse and practically-come in contact with all parts of this upper surface before it can escape into the upper part of the combustion A chamber. The flame therefore not only operatestofheatthe garbage-so asto liberate the gas producing elements therein which result-s in a-gradual cremation ofthe refuse and a reduction of the same to ashes, but

the flame also serve-s to igniteand burn-the con'ibustible gases thus/generated beforethey can escape fromtheuppeijpartoflthe coinbustionchamber to the exterior of the in- .ciiierator iii the building -in which it is installed. This complete destruction of :the garbage and the burningiof-'the combustible Vgases which may be generated prevents the escape of anyodor bearinggases to 'theexterior of the incinerator orof theibuilding and therefore renders the use of the Aincineratoriircitiesand other closelybuiltup iare given off the same are ignited by the `flame of the burner and add their heat there- :toin such a waythat the'successively lower -parts of the garbage which arestill wet or in a non-combustible condition are also successively-heated anddried and converteddnto a. condition of coii'ibust-ibility. As a result of this operation, thegarbage itself furnishes a considerable amountiof the fuel whereby 'heat is geiieratedfor.edecting destructionof .the garbage and :this process continues :from the ytop of the pileidownwardly until the entire mass of garbage .isvcremated and only a comparatively low Vpile of ashes re.

mains resting upon the grate from .which .the same canbe discharged into the ashpit below by dumping the. :grate or otherwise .disposing ofthe same.y

As the ashes are produced on top of the :pile while the garbage isIbeing'consumed by the flame ofthe burnerplaying against the top of the same, the incinerating operation would be' interfered with if the ashes were .permitted tozremain and meansare therefore provided for removing the ashes from the Ltop ofv the pile at Wilh so that the flame of the burnerwill always be able to attack the refuse under the mostl favorable conditions which ,will promote rapid and complete i gravity into theashpit 19 so thattheyy can destruction thereof.v For y.this .purpose the ashes vare-i-aked off Vfrom the top fof the pile ofv refuseA through the lopenings 16 in the inner side wall so that they enter the clearance space 18 through which they drop by be subsequently removed f roni'j the latter through". the "ash voutlet opening V39 thereof which 'is normally closed by the door 40.

`A convenient and practical waytof accomplishing this puiposeyis tol utilizel the ribs 37 on the underside of the yspreading plate`36 as rake teeth r'orrcle'aring members which ribs "upon being oscillatedwhile resting on top of the ashes will `cause 'the flatter to be gradually moved or raked off from the top `of they pile and discharged laterally outward through' the adjacentopenings1161 The means for thus agitating or `operating the ash removing means are preferably combined with elevating means whereby the spreading plate and the burner sections 'mayl be elevated `into their uppermost position preparatory to reloading the combustion chamber with a newbatch of `refuse or garbage, which 'is to be destroyed. This combined agitating `and elevating mechanism c is therefore preferably constructed as follows: c 'I v The numeralv 41' represents anpuprght' gear rack which has its upperpart arranged within the flue 22 :and its lower. partwithin the combustion `clianibei` and has its lower end connected with a lug on the? upper centrall part of the 'spreading "plate 36, as' sli-own in Figures 1 and vThe teeth of this gear rackare engaged by 'an elevating gear pinion 42 which is suitablyk mounted'so that upon turning this pinion-the rack may be Veither raised or lowered; This rotary motion may be imparted to thefgearpinion by" means of a horizontal shaftvor rod 43 which isk arranged in al'segnient shaped iecess44 in the top of the combustion chamber and 4has its inner end connectedwith the gearpinion 42 while its outer end projects outwardly beyond the side of the combustion chamber and is provided with a hand wheel or handle 45wherebythis shaft and the parts associated vtherewith maybe manipulated by the attendant." During the operationV of the apparatus the descent of the spreading plate 36Y together with its ribs 37 and the gear rack 41 descend by gravity inasmuch as the ribs of the spreading plate rest upon the top of the pile and descend in the same measure as v this pile is gradually reduced in height as the result of removing the. ashes therefrom. The gear rack and gear pinion 'are so mounted on theupper part of the combustion chamber that the handle 45 and operating shaft 43 may also be utilized for agitating thefspreading plate 36 and its shaking ribs 37 by swinging the rod or shaft 43 horizontallyback and forth in the pocketor recess 44. In order to permit of this action and Istill enable the burner plate and partsassociated thereto to be raised and vlowered without interference,` the gear rack 41 is made of angular form incross section, preferably square, vand guided above and below .fthe pinion in guide bushings 46, 47

which are journaled vin the upper and lower bearings 48 and 49 Varranged above and belowfthe pinionw42 and forming part `of a vbracket 50 which is mounted on the top of the combustion chamber and extends across' the lower end of the `vapor outlet flue 22.;

Each of these bushings 46 and 47 is provided with an annular flange 51, the flange of the upperbushiiig engaging with a'downwardly facing shoulder 52 on the upper bearing and the {iange 51 of the lower bushing enf gaging with an upwardly facing shoulder v bidonl the lower bearing and each of` these` bushings being also .provided with an axial opening 54 which is square in cross section 'so that itiits the gear rack .41 and permits the latter to slide in the bushings but compels the sanieto turn therewith in the bearings`48` ai id"49. Between fthe upperand lower bushings 46 andk 47 is arrangeda yokeA 54 which has an. angular seat 55 which en# gages with theexterior of the gear rack 41 and permits the Vlatter to slide vertically in thisyoke, but compels the same to turn therewith.

upper andlower bushings 46and 47 so that this yoke is held against vertical displacec 'nient but is capable of turningwvith the gear rack.

The gear Y pinion`43 is arranged between ltwo bearings 56, 56 on the yoke 54 and the inner part of the shaft43 which carries this pinion is journaled in these bearings. 56. Bythis means* a rotation of theoperat-ing shaft 43 in one direction or the other will cause the pinion to raise kand lower the racky 41V and the spreading plate 36 and parts associatedtherewith while upon swinging the outer end ofthe operating shaft horizontally backand forth in the pocket or recess 44, the yoke 54 together with the pinion, rack, spreading plate and yribsrf37 This yoke bears at its upper and; jlower ends against the opposing ends of the Y toi-the, varying heights of the pile of refuse in' the .combustion chamber and also per- `vl`niitting oi'' producing-the agitating effect of the yspreader and its ribs whereby the ashes areraltedoff or discharged from the'top of thepile, as beforedescribed. Y

In view of fthe fact that a considerable part olic this elevating and agitating niech anisin `is arranged within'the upper pait'of the combustion chamber and extends upwardly into lthe gas flue 41,'these parts are concealed fromview and doV not eneroach upon anyspaccuwhich is required tor-other purposes thereby not only simplifying` the constructioniofitlieapparatus but also renderingathe'same very; neat andiattractive in appearance and thus the same isparticularly suitable .torehousehold use.

Inorderto permit of'holding the elevating and agitating mechanism in place-while thefspreading plate Bltand parts associated therewith are in their highest. position', a

locking device is provided Awhich Willleave the attendant tree vto lill the combustion chamber withfrefuse. This locking mechanism ispreferably combinedV with the elevating. and agitating `mechanism so that-.practically `no :extra wparts: are required for this purpose. In its preferredflorm this `locking nieclianisn'itconsists ol? allockiugliig. 5T-which proj ectslaterally from the lower y part of the gear: rack,- anda locking-hook 58 arranged on ithe niidersideof the loweiwbearing 49 ofthe bracket. SiO. The Vrelative arrangement ot' the locking lug 57 and the loolinghook 58 is suclitliat upon turning vthe gearraclrinto one position, for instance whenswinging the operating bar to its extremerright hand position as. indicatedby full lines in Figure 2, Athis rack and :the parts;associated `therewith may. be raised Aand lowered efreely.

scribed. 'lhe spreading plate and the burner may therefore by this means be .readily lockedv in Aan elevated :position so that the attendant can freely introduce a new batch or mass oi' garbage Tinto thecombustion cl'iamber around the `burner andA underneath `the `spreading. *plate7 preparatory to again: unlocking the gear rack from the bracket and permitting the spreading plate tobe lowered together with tlie burner until y this plate againfrests byy gravity upontlie top sliding 1 oircuniterentially yon itlie vperipheryot' the collar. The-operating shaft, projects through tlieslot 59 and;through `thevshutter A :and the latter moves with tliesliaftluring its horizontali rocking movementsbut always covers the slot 59 to prevent the-escape ot' lilly gils.

This incinerator not only permits of com-y plet-ely destroying-thegarbage in a manner which-ispractically lodorless and yields a minimum of ashesbiit the same isalso very compact in construction, very neat and attractive inappearanceand the several parts .can beeasily manipulated 4and are not liable to `get ont oi order.`
